Ocean Optics CUV-TLC-50F - Manual (Page 15)

2: Operation
Caution
Be sure to first loosen the fiberoptic SMA 905 connection, so as not to apply torsion
to the fiber.
This adjustment varies the position of focus in the sample when desired for specific experiments, or to
compensate for lens aberrations to maximize optical throughput. For normal operation the distance
between the knurled ring on the horizontal fiber position knob should be set 1/8 inch from the knurled
ring on the first lens holder (see the following figure).
Imaging and Collimating Lenses
Converting an Imaging Lens into a Collimating Lens
The second lens of the imaging lens system is simply snapped onto the end of a collimating lens (see
figure above). To remove the second lens, use a piece lens tissue to prevent your fingers from touching
the lens. With the lens tissue in your hand, firmly grasp the second lens holder and snap it off of the
collimating lens.
System Operation
► Procedure
1. Turn on the power to the CUV-TLC-50F system using the switch located on the left side of
the rear panel of the temperature control unit.
2. Place the liquid sample in a standard 1 x 1-cm square fluorescence cuvette to reach a height
of 22 mm.
